BMPROVEMENT IN DRAFT-PIPES FCR AERATEVD LIQUIDS.

Specification forming part of Letters Patent No. 134,710, dated anuary 7, 1873.

To all whom it may concern.-

Be it known that I, OscAR F. STEDMAN, of Westfield, in the county of Chautauqua and State of New York, have invented a new and valuable Improvement in Draft-Pipes for Aerated Liquids; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation of the same, reference being had to the annexed drawing making a part ot' this specification, and to the -letters and figures ot' reference marked thereon.

Figure'l of the drawing is a representation of' a side view of my invention 5 and Fig. 2 is a sectional view of pipe and valve.

This invention has relation to means for regulating the discharge of soda-water, beer, and other aerated liquids, according to the amount of pressure under which it is being delivered; and it consists in the construction and novel arrangement of a draftpipe and an adjustable cap covering the discharge-orifice, as. hereinafter described.

In the accompanying drawing, the letter A designates a stop-cock with a milled disk-handle, B. C indicates the draft-pipe, made long enough to reach the bottom ofthe tumbler or other vessel in which the liquid is designed to be drawn. On the exterior of this pipe, near its end, a screw-thread7 a, is formed to engage with the thread of a nut or sleeve, b, placed on the pipe at this part of its length. D indicates the delivery valve or cap, which is secured to the sleeve b by means of arms c or other suitable devices. The valve D s usually made in the form of a disk, with a conical or convex upper surface, designed to approach the orifice of the draft-pipe closely enough to cause thefliquid to be injected with force into the receiving-vessel, the degree of proximity being readily adjusted to the amount of' pressure by means of the sleeve b.

It is found in the use ot' this draft-pipe that the size of the discharge-orifice in proportion to the pressure has much to do with the quality of the beverage drawn, and that its form is adapted to produce in this respect satisfac- Jtory results.

I do not desire to confine myself to the pre cise means shown of effecting the adjustment of the cap, as it may sometimes be desirable to use other devices.

What I claim as new is- In apparatus for dispensing aerated liquids, the long tapering draft-pipe provided with the adjustable convex disk D covering the discharge-orifice, and adapted to be inserted in the bottom of a receiving-vessel, substantially as specitied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

OSCAR F. STEDMAN.
